I was being very dumb at first and even had to share the image with M because I couldn’t work out how you had done this. Then he pointed out that we were seeing the sheets. You, Penny, are a complete genius. Truly brilliant image

No you haven’t missed anything–it hasn’t worked for me yet. To be honest it’s counter-intuitive for me to try to block it in the throws of coming & pushing etc. (basically I forget most of the time lol)…but I’m going to try to make a more conscious effort. I’ll let you know if there’s a significant update. 🙂
